Method for manufacturing louvers of a shutter

ABSTRACT

A method for manufacturing louvers of a shutter is disclosed. In the method, a roll of paper is cut into several paper sheets according to the weaving width. The paper sheets are soften with water, then the paper sheets can be shaped up after rubbing. The paper sheets are rubbed into several paper threads by a rubbing machine. Those paper threads are weaved to be a paper cloth by a weave machine. The paper cloth is sized and dried by heating so that the paper cloth is solidified. According to the shape of the louver, the paper cloth is cut into several paper louvers having a predetermined shape of the louvers of shutter. Two holes are drilled in the two ends of each paper louvers, so each paper louvers can be integrated in shutter. After that, each paper louvers is shaped by molding, a curved cross-section of paper louver is formed then each paper louvers can resist side pressure.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention generally relates to a method for manufacturing louvers of a shutter, and more particularly to a method for manufacturing louvers of a shutter by using paper or nonwoven fabric.

2. Description of the Related Art

In a home or office environment, some windows are installed inside the house to save the power energy. By the transmittance of the window, the house is not required to turn on the light to have enough illumination. When the sunshine is too hot and the people need privacy, most of people will install a shutter in a window to separate the vision and the sunshine. However, the louver of the most shutters is made by aluminium (or plastic). When the sun shines the light inside the house, the louver made by aluminium or plastic will absorb the heat and effect the result of the heat insulation. In addition, the louver made by aluminium costs too much and is hard to recycle after damage. Because the louver is hard to re-fabricate, it would cause the environment problem. Therefore, how to design a louver, which hardly absorbs heat, facilitates recycling and does not cost too much, is a big issue required to overcome.

SUMMARY OF THE INVENTION

According to the drawbacks described above, the applicant develops a new louver for a shutter to overcome the problems in the prior art.

The object of the present invention is to provide a method for manufacturing louver of shutter by using paper or nonwoven fabric.

According to the object described above, in the method of the present invention a roll of paper (such as recycle paper) is first cut into a plurality of paper sheets according to the weaving width. Then, the paper sheets are soften with water so that the paper sheets can be shaped up after rubbing. The paper sheets are rubbed into a plurality of paper threads by a rubbing machine. The plurality of paper threads are weaved to be a paper cloth by a weave machine. The paper cloth is sized and dried by heating so that the paper cloth is solidified. According to the shape of the louver of the shutter, the paper cloth is cut into a plurality of paper louvers that have a predetermined shape of the louvers of shutter. There are two holes drilled in the two ends of each paper louvers so that each of the plurality of paper louvers is able to be integrated in shutter. After that, each piece of the paper louvers is shaped by molding, a curved cross-section of the plurality of each of paper louvers is formed so that each of the plurality of paper louvers is able to resist side pressure. Therefore, several paper louvers of the present invention are formed.
